— The parameters affecting particle injection in a high pressure powder fuel injection system were verified by using computational particle fluid dynamics (CPFD). The particles were coal (í µí± í µí± =175 μm, ρ s = 1350 kg/m 3), and the simulation was performed by changing the clearance between the roller and the hose and by changing the total pressure drop. Also, the wall erosion of the hose was confirmed by changing the clearance. As the clearance decreases from 10 mm to 1 mm when...

— The effectiveness of microwave-assisted preparation of N-alkylisatin--thiocarbohydrazones, where alkyl group is methyl and ethyl, was evaluated. The corresponding N-alkylisatin--thiocarbohydrazones were predominantly obtained by TCH and N-alkyl substituted isatin in molar ratio 3:1. Reactions of carbonyl-amine condensation were performed in water acidified to pH 1.5 as a solvent system. Reaction mixtures were exposed to microwave irradiation under 300W and pressure 200 psi, for a...

— Base isolation (BI) is a technique that has been used around the world to protect the building structures from the damaging effects of earthquake. The installation of isolator in building at base level considerably increases the time period of the structure, which means it reduces the possibility of resonance of the structure giving rise to better seismic performance of the building. The analysis is performed to compare the effectiveness of base isolation in regular and irregular...

— The phenomenon of photovoltaic systems is based on the principals of semiconductor physics and they operate with a semiconductor element, such as silicon. Photovoltaic cells can generate electricity only when they receive a certain amount of photon energy and thus they convert only a fraction of the solar irradiance, which is received from the sun in the form of electromagnetic radiation in the electromagnetic spectrum, into electrical energy. The remaining radiation is stored as heat in...
